Step 36

Check that the controls move in the correct direction and that

their throws correspond to the following when measured at

their widest points.

Ailerons

- 25mm up/20mm down

Elevator

- 35mm up/30mm down

Rudder

- 60mm each way

Flap

- 20 Degrees (Take Off)

- 45 Degrees (Landing)

Step 37

Check the center of gravity to ensure the model

balances correctly 136mm back from the Leading edge

at the crank in the wing. We needed 1.7kg of nose

weight to achieve this on our prototype. Secure any

weight well to avoid it coming loose due to vibration.

Step 38

The wing panels are joined with the large diameter aluminium tube supplied, and the wing is then mounted

to the fuselage using four M4 bolts. The tailplane halves mount to the fuselage using the smaller diameter

aluminium tube supplied and two countersunk M3 screws.

Step 39

For first flights we recommend the use of a large and open flying site with a good length of runway, not

because the model is hard to fly, but in the event of a minor problem or an engine cut, having plenty of

runway available can make the difference between a safe landing and a wrecked model. If there is going

to be a problem it is most likely to occur during the first few flights, so any extra time required to travel to a

good open site can prove to be well worth the effort.

Do carry out thorough range checks before flying, both with the engine off and running, and check for any

radio interference caused by the engine, throughout the rpm range. Also check all the controls, ensuring

that they operate in the correct direction and with the correct movements, and that there is no slop or lost

motion in any of the linkages and that all clevises and balljoints are secure. Any clevises being used must

have keepers fitted for added security. Finally check the retracts and doors to make sure they are operating

correctly and that no air leaks have developed.

Once happy, refill the fuel and air tanks, and once the engine is running and warmed up check that it will
